The Electoral Commission advice is conservative, in my opinion. “Parliamentary” material that has an electioneering effect can also be an election advertisement, but if I had a large stock of pamphlets I did not want to count against my budget I might think it worthwhile going for a declaratory judgment. Of course Labour will not want their stupidity dissected over days in public, and the other side is enjoying the perpetrators’ misery.

How does the line go – “O what a tangled web [they] weave when first [they] practice to deceive”?
